Description

  The present invention relates to a railway vehicle driving operation recording apparatus for recording and monitoring a railway vehicle driving operation.

  Conventionally, as shown in FIG. 3, a railway vehicle driving operation recording apparatus for recording driving operations has two driving vehicles 1F and 1R for the front and rear cars for improving redundancy and reliability. Central devices CPU1 and CPU2 are installed. One CPU1 serves as a control unit 101 and a transmission / display unit 102, and the other CPU2 includes a control unit 103 and a recording unit 105 that records a driving operation of the handle 104. The operation signal of the handle 104 is input to both the CPU1 and CPU2 at the same time. The CPU 1 is connected to the terminal device 106 of some intermediate vehicles 1C and the CPU 1 installed in the driver's cab of the other leading vehicle through the network system 107 to communicate various information, and the display device 108 is displayed. The control unit 103 of the other CPU 2 receives driving operation information from the handle 104 and causes the recording unit 105 to record the driving operation information in real time.

  Conventionally, recording is performed by the recording unit 105 mounted on the driver's cab (here, described as the driver's cab 1F) that performs the driving operation with the handle 104. And when recording operation with a plurality of devices in the train organization, it is mounted on the operating cab 1F side where the operation is performed in order to avoid inconsistencies in the recorded data at both cabs 1F and 1R due to transmission delays between vehicles. The storage unit 105 stores data once and then performs a complicated process of transferring the data to the recording unit 105 mounted on the other cab 1R.

  In general, in the case of a railway vehicle, when an accident such as a collision occurs, the leading vehicle is likely to be damaged. Since the driving operation is normally performed at the cab 1F of the leading vehicle, if the configuration is such that the driving operation is recorded only with the leading vehicle where the driving operation is performed, the recording device may also be damaged in the event of an accident. It is necessary to ensure the redundancy of the operation record by a method such as simultaneously recording the operation operation at a plurality of locations in the train.

  However, in the conventional railway vehicle operation recording apparatus described above, when recording is simultaneously performed at a plurality of locations in the train organization, the transmission system is FSK having a communication speed of about 100 kbps, or an arc net having a higher speed of 2.5 Mbps ( Because it is based on the ARCNET (Attached Resource Computer NETwork) in English, the communication speed is slow compared to Ethernet (trade name) -based communication capable of ultra-high-speed communication of 100 Mbps and 1 Gbps, which has been widely used for network communication in recent years. Due to the transmission delay between the vehicles, the recorded data of the two cabs are inconsistent, and there is a problem that the reliability of the data cannot be ensured even if the data is recorded at a plurality of locations.

Further, when performing finer recording, the recording capacity increases as the recording sampling period is shortened. However, since the data transfer capability is not sufficient in the conventional in-vehicle network, problems such as an increase in transfer time and an increase in processing load occur in the recording processing of large-capacity data, the recording capacity is increased, and the recording redundancy is the same. There is a problem that it is difficult to ensure the property.

  Another feature of the present invention is a railcar driving operation recording device for transferring data in a railcar through a high-speed network within a train, wherein a pair of central devices are installed in each of the front and rear vehicles. A main recording device that records driving operation signals from the driver's cab in real time is provided in each of the pair of central devices, and the pair of central devices of the front and rear cars is a two-system high-speed network in the organization The operation signal from either cab is transmitted to each of the other pair of central devices in each of the two high-speed networks within the organization and recorded in each of the main recording devices. It is.

  Moreover, according to the railway vehicle driving operation recording apparatus of the present invention, the influence of the transmission delay in the train is reduced by applying the two systems of the train internal high-speed network for inter-vehicle transmission, and the operation is performed. It is possible to reliably ensure the identity of the recorded data between the two systems of recording devices mounted on the platform and other cabs, and to improve the recording accuracy.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  [First Embodiment] FIG. 1 shows a railway vehicle driving operation recording apparatus according to a first embodiment of the present invention. The railcar driving operation recording device of the present embodiment has two central devices 2A and 2B in each of the driver's cabs 1F and 1R of the front and rear cars in the train formation, and two intermediate devices 1C and 2 A pair of terminal devices 3A and 3B are installed, and each vehicle is connected by two systems of high-speed networks 4A and 4B in the train in order to provide redundancy.

  The high-speed networks 4A and 4B within the organization are based on Ethernet (trade name) and have a communication speed of 10 Mbps to 100 Mbps. The network cable is a one-pair, two-wire type with a thicker shield to increase noise resistance. The network communication system is a bus-type simulated token system as described in Patent Document 1 described above to improve real-time performance. Further, the operation information of the handle 11F at the driver's cab 1F during the driving operation or the handle 11R at the driver's cab 1R on the opposite side is collected at a fine sampling period of millisecond order and is simultaneously recorded in the recording devices 12A and 12B. Is recorded. The intra-composition high-speed networks 4A and 4B have a sufficiently short transmission delay performance with respect to this sampling period.

  In the case of the present embodiment, the operation information such as the operation of the handle 11F on the cab 1F and the switch operation during the operation is recorded on the recording devices 12A of the central devices 2A and 2B on the cab 1F as described above. , 12B and simultaneously recorded in parallel, and data is transmitted to the terminal devices 3A and 3B of the intermediate vehicle 1C through the high speed networks 4A and 4B within the train with almost no time lag, and simultaneously recorded in the recording devices 13A and 13B. In addition, data is transmitted to each of the central devices 2A and 2B in the driver's cab 1R of the rearmost leading car with almost no time lag and is recorded in parallel on the recording devices 12A and 12B.

  Thus, according to the railway vehicle driving operation recording device of the present embodiment, the recording devices 12A and 12B mounted on the two cabs 1F and 1R, respectively, and the recording devices 13A and 13B on the intermediate vehicle 1C are almost simultaneously. The driving operation of one handle 11F can be recorded. Further, by recording the same contents with a recording device mounted on each vehicle in the train, it is possible to ensure the redundancy of the driving operation record for the entire train.

  When the driving operation of the cab 1R of the rear leading car is valid, the recording devices 12A and 12B mounted on the cabs 1F and 1R, respectively, and the recording device 13A on the intermediate vehicle 1C, contrary to the above. , 13B, the operation of the other handle 11R can be recorded almost simultaneously.

  Further, if the data recorded in the recording devices 12A, 12B, 13A, and 13B can be read out for each vehicle, if the data of a certain vehicle is damaged, the data of the other vehicle is adopted to Read redundancy is also improved.

  Further, as in the present embodiment, the in-composition networks 4A and 4B are configured in a double system, and driving operation recording is simultaneously performed at two locations in the same vehicle, thereby further improving the recording redundancy. Thus, even if one of the network systems fails, the operation can be continued by switching to the other network system, and the system reliability is high. However, when the demand for redundancy is more lenient, the system can be configured by only installing the recording devices 12A and 12B in the front and rear vehicles, and not installing the terminal devices 3A and 3B of the intermediate vehicle 1C. Can be simplified.

Instead, the data is transmitted and recorded on the recording device 12. On the contrary, when the rear cab 1R side is effective, the operation information such as the operation of the handle 11R on the cab 1R, the switch operation, etc. is also stored in the central device 2 on the cab 1R side. In addition to recording in real time in the recording device 12, the data is transmitted and recorded in the terminal recording device 13 of the intermediate vehicle 1C through the intra-compartment high speed network 4 with almost no time lag, and in the cab 1F of the leading car on the opposite side. Data is transmitted to the central device 2 with almost no time lag and is recorded in the recording device 12.
